Abstract
The trophoblast epithelial-to-mesenchymal transition (EMT) is a procedure related to embryo implantation, spiral artery establishment and fetal-maternal communication, which is a key event for successful pregnancy. Inadequate EMT is one of the pathological mechanisms of recurrent miscarriage (RM). Whole-exome sequencing revealed that the mutation of bromodomain PHD-finger transcription factor (BPTF) was strongly associated with RM. In the present study, the effects of BPTF on EMT and the underlying mechanism were investigated. We found that the expression of BPTF in the villi of RM patients was significantly downregulated. Gene Ontology (GO) analysis revealed that BPTF participated in cell adhesion. The knockdown of BPTF prevented EMT and attenuated trophoblast invasion in vitro. BPTF activated Slug transcription by binding directly to the promoter region of the Slug gene. Interestingly, the protein levels of both Slug and BPTF were decreased in the villous cytotrophoblasts (VCTs) of RM villi. In conclusion, BPTF participates in the regulation of trophoblast EMT by activating Slug expression, suggesting that BPTF defects are an important factor in RM pathogenesis.

Abstract
Background Immunotherapies targeting peripheral natural killer (pbNK) cells in unexplained recurrent miscarriage (uRM) remain controversial. We hypothesized that the change in pbNK cell count might be a result of innate immune responses rather than a cause. Objective To explore whether the pbNK count is significantly different in women testing positive than those testing negative for commonly studied autoimmune markers. Methods Peripheral blood samples were collected from 302 eligible patients with uRM for the antinuclear antibody (ANA) testing determined by the enzyme-linked immunosorbent assay (ELISA), anti-thyroid peroxidase antibody (TPO-Ab) testing and anti-thyroglobulin antibody (Tg-Ab) testing determined by the chemiluminescent immunoassay, and pbNK cell testing determined by flow cytometry. The patients were divided into two groups according to the pbNK normal range, and the comparative analysis entailed an examination of the prevalence rates of autoantibodies within the high pbNK group and the normal pbNK group, followed by a comprehensive investigation into the potential correlations between autoantibodies and pbNK cells. Results There was a positive association between TPO-Ab positivity and high pbNK cells (p=0.016, OR=5.097, 95% CI 1.356-19.159), while there was a negative association between ANA positivity and high pbNK cells (p=0.013, OR=0.293, 95% CI 0.111-0.773). TPO-Ab-positive patients had a higher pbNK cell count compared with TPO-Ab-negative patients, while ANA-positive patients had a lower pbNK cell count compared with ANA-negative patients. Conclusion The change in pbNK cell count may be a consequence of immune responses, and there should be careful consideration in applying it as an immunotherapeutic index.

Abstract
Recurrent pregnancy loss (RPL) or recurrent miscarriage is the failure of pregnancy before 20-24 weeks that influences around 2-5% of couples. Several genetic, immunological, environmental and physical factors may influence RPL. Although various traditional methods have been used to treat post-implantation failures, identifying the mechanisms underlying RPL may improve an effective treatment. Recent evidence suggested that gene expression alterations presented essential roles in the occurrence of RPL. It has been found that long non-coding RNAs (lncRNAs) play functional roles in pregnancy pathologies, such as recurrent miscarriage. lncRNAs can function as dynamic scaffolds, modulate chromatin function, guide and bind to microRNAs (miRNAs) or transcription factors. lncRNAs, by targeting various miRNAs and mRNAs, play essential roles in the progression or suppression of RPL. Therefore, targeting lncRNAs and their downstream targets might be a suitable strategy for diagnosis and treatment of RPL. In this review, we summarized emerging roles of several lncRNAs in stimulation or suppression of RPL.

Abstract
BACKGROUND Unexpected and repeated miscarriages in a woman's life cycle can be a mental and physical burden and lead to post-traumatic stress disorder. However, women may also experience inner growth with such experiences. METHODS This study was qualitative descriptive research examining the experiences of South Korean women who had recurrent miscarriages three or more times. RESULTS The average age of the participants was 34.6 years, and the average number of recurrent miscarriages was 3.87. Additionally, five themes were identified as follows: (1) Confusing as if in muddy water, (2) Self-examination of past daily life, (3) Empathy and comfort in homogeneous groups, (4) Religious beliefs that include the lost fetus, and (5) Transforming for internal growth. CONCLUSION Based on the results of this study, intervention strategies need to be implemented to support the inner growth of women who have experienced recurrent miscarriages.

Abstract
UNLABELLED The Tommy's National Centre for Miscarriage Research aims to support the diagnosis and treatment for couples suffering from recurrent miscarriage. Tommy's Net is an electronic data gathering tool, collecting miscarriage data and links with hospital Clinical Information System databases. The gathering of patient reported data is an important aspect, especially as data relating to pregnancy and miscarriage events are often left unreported. METHODS Both traditional paper-based and electronic patient reported outcome (ePRO) solutions have been explored to improve response rates, minimize data redundancy and reduce burden on staff. Popular ePRO survey solutions have been compared, including REDCap, SurveyMonkey, Qualtrics and LimeSurvey. RESULTS LimeSurvey was selected as the most appropriate solution as it provided self-hosting capability, SMS integration and ease of use. CONCLUSION We have implemented a LimeSurvey based ePRO system for collection of baseline and follow-up data for participants on the Tommy's study.

Abstract
Intravenous immunoglobulin (IVIg) has a documented clinical effect in many autoimmune diseases and has so far been tested in >10 randomised controlled trials (RCTs) in women with recurrent pregnancy loss (RPL). The results of the RCTs have, however, been very divergent. In meta-analyses of all trials, no significant impact on live birth rate has been reported. In contrast, in sensitivity analyses, IVIg significantly increased live birth rates when initiated prior to conception and it had a borderline significant therapeutic effect in women with secondary RPL. Higher dosages of IVIg and serological signs of autoimmunity in the treated patients tended to increase the success rate after treatment. A follow-up study of patients from our recent RCT also supports a significant therapeutic effect in patients who had received IVIg before conception. The lessons learned from the published trials and meta-analyses should be incorporated in the design of future RCTs of IVIg in the treatment of RPL.

Abstract
Background The prognostic value of peripheral natural killer (pNK) cells, as a screening test in women with recur-
rent pregnancy loss (RPL) and unexplained infertility, is still a matter for discussion. The purpose of this study was to
compare the percentage of circulating CD56+NK cells, CD69 and perforin markers between women with unexplained
infertility and RPL with the healthy control group. Materials and Methods In this case-control study, the percentage of CD56+NK cells and activation markers (CD69
and perforin levels) in the peripheral blood were measured in 25 women with unexplained infertility, 24 women with
idiopathic RPL and 26 women from the healthy control group, using specific monoclonal antibodies by flow cytometry. Results The percentage of CD56+NK cells was significantly higher in patients with infertility in comparison with
the healthy control group (P=0.007). There were not significant differences either in the total number of CD56+cells
between the RPL group and the control group (P=0.2) or between the RPL group and the infertile group (P=0.36).
The percentage of CD69+lymphocytes in RPL group was significantly higher than in the infertility group (P=0.004).
There was a statistically significant difference in Perforin levels between RLP and control (P=0.001) as well as RPL
and infertile (P=0.002) groups. Conclusion An increased percentage of CD56+NK cells in patients with unexplained infertility, an elevated expression
of CD69 on NK cells in patients with RPL and infertility and a high level of perforin on CD56+cells in the RPL group
might be considered as immunological risk factors in these women.
